Answer:
3.0
Step-by-step explanation:
The angle, its opposite side, and the hypotenuse are given. Then the relevant trig relation is ...
Sin = Opposite/Hypotenuse
sin(21°) = x/8.3 . . . . . . . . . . . . . . . . . . use the given values
x = 8.3·sin(21°) ≈ 8.3×0.3584 . . . . . . multiply by 8.3
x ≈ 3.0
Answer:
4
Step-by-step explanation:
6/7 divided by 3/14 is 4.
Find common denominators.
6/7 would be changed into 12/14.
3/14 would stay the same because its denominator is already 14.
12/3 = 4
Therefore, 6/7 divided by 3/14 is 4.
Answer:
8
Step-by-step explanation:
y = 7 - x
y = 7 - (-1)
note: a negative plus a negative equals a positive.
y = 7 + 1
y = 8
The negative in a = -2 for answer A represents a reflection over the x-axis.
What does the cosine graph usually look like?.....It goes through point (0,1) and decreases.
The graph shown goes through point (0,-2). Since there are no vertical or horizontal shifts, the graph has an amplitude of 2 and reflects over the x-axis.
a=2 for answer D does not represent the reflection over the x-axis.
